Any format.
One memory system.
Knowledge doesn't come in just one format. Medical students need anatomical images. Language learners need audio clips. Physicists need vector-rendered LaTeX. Reminda handles all of them — in a single, encrypted memory vault.

Input:
\int_0^\infty e^{-x^2} dx = \frac{\sqrt{\pi}}{2}
∫₀^∞ e^(-x²) dx = √π/2
Input:
E = mc^2
E = mc²
Input:
\hat{H}|\psi\rangle = E|\psi\rangle
Ĥ|ψ⟩ = E|ψ⟩
Audio intelligence
Hear it. Say it. Remember it.
Auditory memory is a fundamentally different neural pathway than visual memory. Reminda's audio system lets you pair every flashcard with native pronunciation clips, personal voice recordings, or professor lecture snippets — training both recall channels simultaneously.
Native Speaker Audio
128 kbps — High Fidelity
Record your own voice
Compare your pronunciation against native speaker clips during SRS sessions.
Native speaker clips
Pair any vocabulary card with high-definition native pronunciation from 50+ languages.
Professor lecture snippets
Embed audio excerpts from lectures directly onto relevant study flashcards.
Offline playback
All audio files sync locally via IndexedDB — available on flights, subways, and offline.
